WICHITA, Kansas – After less than two days, the jury in the Marquis Marshall murder trial found the 20-year-old guilty of killing two at a Wichita Dollar General last November.

Video surveillance showed 79-year-old Henry Harvey and 22-year-old Zachary Hunt died when they were shot inside the store.

Harvey was at the counter buying candy for his grandchildren when he and Hunt were both shot several times.

Marshall was arrested several days later in a traffic stop.

He was charged with capital murder, but prosecutors were not seeking the death penalty.

Tuesday morning, Marshall appeared in front of the judge looking down from time to time as several witnesses took the stand to testify.

Prosecutors addressed the jury beforehand telling them they had key evidence, including surveillance video to prove that Marshall was the suspected gunman.

“Yes, I think it’s important, it’s something we rely a great deal on, and I hope criminals take into account. They should be less inclined to do crimes of violence and in general because there is a surveillance camera somewhere that will catch them in the act,” said Marc Bennett, Sedgwick County District Attorney.

The prosecution rested its case Wednesday morning and the defense rested without calling any witnesses.

The jury got the case at 2:22 p.m. and the deliberations lasted until 3:25.

Marshall never took the stand in his defense, but defense lawyers say the surveillance video was not clear enough for a conviction.

“It is not clear,” said defense attorney Ron Evans. ” And you can’t see. You can’t identify anybody. Certainly not Mr. Marshall from that video.”
